I tried the grayscale on X7 but I was not impressed by the result. May be I didn’t get correct image manipulation or what, the result look worst than just doing engraving with dithering. E5 runs on LaserCad and there is no “grayscale “ option from the drop down menu. Again, it didn’t work out good so far. May be it works on drawing but not an jpg image that I need to do more test next week
